Essentials Level A

Every module in both levels uses scaffolds and tools as permanent supports, teaches estimation as the student's own way of checking their work, and advances a place value / number sense progression built module to module.

Level A (Modules 1–6) — Number sense and whole-number arithmetic: comparing quantities, place value, and adding, subtracting, multiplying, and dividing multi-digit numbers.

Level B (Modules 7–11) — The same approach extended beyond whole numbers: money and decimals, percent, tax and tip, fractions for recipes and measurement, and basic ratios and proportions.
